Not enter VSR routine when lan91cxx_start executed

Hello,

Since I enabled next option,
CYGHWR_NET_DRIVER_ETH0_ADDRS
lan91cxx driver began to work.

But when lan91cxx_start routine is ececuted,
although IRQ-3 line(=ethernet interrupt signal) is asserted,
it looks like not entering into cyg_hal_default_interrupt_vsr(SH VSR routine).
On the other hand Timer interrupts are entering into that routine.

Why this happens ?
Do I need to set any options ?

Please help me if you know the reason.

Masahiro Ariga
